SPECIFICATION forming part of Letters Patent No. 560,791,dated May 26,1896.

` 'Application filed May 21, 1895. Serial No. 550,112. (No model.)

To @MZ` whom, it may concern:

Be it known that LMARTIN A. HAGER@ citi- Zen of the United States,residing atEsdaile, in the county of Pierce and State of W'isconsin,have invented a new and useful Pump At-` tachment, of which thefollowing is a specification.

This invention relates to an improvement in pumpy attachments.A

The object of the present invention is to renderfeasier and lighter theprocess of pumping by supporting and relieving the pumping apparatus orpump-rod in such manner `that the pump-rod will require less power tooperate it and the strainand jerking incidentto the starting and rapidoperation of the pump will be obviated.

Withfthe above end in view the invention consists in certain novelfeatures and details of construction and arrangement of parts, ashereinafter fully described, illustrated in the drawings, and pointedout in the claim.

In the accompanying drawings, Figure 1 is a side elevation of a pump,showing also my improved attachment applied thereto. Fig. 2 is anenlarged perspective view of the im- Fig.4 3 is a detail perspectiveview of one of the adjustingscrews for regulating the tension of thesprings which support the pump-rod.

Similar numerals of reference designate corresponding parts in theseveral iigures of the drawings.

Referring to the accompanying drawings, 1 represents an ordinary pump,which may be of any usual or preferred construction, and 2 indicates thepump rod or piston, which reciprocates through an aperture in the upperend of the pump-stock and which has a {iattened or polygonal upperportion.

3 indicates a bracket attached to the top of the pump and extendingupwardly therefrom to receive the pump handle or lever 4, pivotedtherein and connected to the pump rod or piston, said bracket 3 beingextended above the pump handle or lever to form an upper bearing for thevertically-reciprocating pump rod or piston, such extension forming alsoa support for my improved attachment, which will now be described.

The attachment comprises an open rectangular frame, made for the mostpart from iron or steel, composed of side bars 5 and 6, a lowerconnecting-bar '7, and an upper connecting and guiding frame bar 8,which will be sev erally described. The side bars 5 and 6 extend invertical and parallel relation to each other, one of said bars 5 beingextended considerably below thelower extremity of the other bar 6 andbelowkthe cross-bar 7 downward a sufficient distance to form a brace,which is firmly secured to the pump-stock, as indicated at 9, forsupporting the attachment and sustaining the same in proper position.The lower cross-bar 7 is provided at its ends with angular feet 10,through which it is riveted to the side bars 5 and 6 and is alsocentrally perforated to admit of the passage of the reciprocatingpump-rod. As a further means of securing the attachment in position, thelower cross-bar 7 is perforated to receive the upper ends of a staple11, which passes around beneath the upper extension of the bracket 3,above referred to, and is screw-threaded at its ends to receive suitableclamping-nuts, as shown. By the aid of the staple or loop 11 and thedownward extension of the side bar 5, connected with the pumpstock, asdescribed, the attachment is effectually and firmly supported in place.

The upper connecting-bar is composed of an oppositely-disposed pair ofmetallic straps 12, which are provided centrally withoppositely-extending curved portions 13, forming a guiding-eye, throughwhich the pump-rod or the rod which extends up to a windmill crank-shaftis adapted to reciprocate. The straps 12 are preferably formed from asingle strip of metal, being riveted between the upper ends of the sidebars 5 and 6, as shown. ,The upper extremities of the side bars are bentinwardly over and above the straps 12 and perforated to permit thepassage of an oppositely-disposed pair of adj listing-bolts 14, thelower ends of which are hooked, as at 15, to receive the upper ends of apair of spiral springs 16, arranged within the rectangular frame andspaced apart to permit the passage of the pump-rod y between them. Thelower ends of the springs 16 are connected by means of a crossbar orlink 17, perforated at its opposite ends to receive the lower hooked IOOends of said springs, and also provided with a central perforationadapted to receive the pump-rod and having a set-screw 1 S, by means ofwhich the relation between the cross-bar 17 and the pump-rod may beiiXed at any desired point. The central perforation of the cross-bar orlink 17 is rectangular to receive the polygonal or iiattencd portion ofthe pump-rod, and the side clamp 18 engages one of the side facesthereof. The ends of the straps 12 are spaced sufficiently apart toreceive the upper ends of the springs 1G, and the tension of saidsprings may be adjusted either by tightening the nuts of theadjusting-screws at the tops of said springs, or by adjusting theposition of the cross-bar 17 with relation to the pump-rod by means ofthe setscrew 18.

By means of the construction above described the tension of the springsmay be utilized for the purpose of assisting in the operation ofpumping, the idea being to equalize the power required for elevating orlowering the pump-valve and pump-rod. The longer the stroke of thepump-rod and the greater the amount of water lifted at each stroke thetighter should the springs be adjusted, and vice versa, where the strokeis a short one and only a small quantity of water is lifted at a time.

The device is simple in construction, effective in operation, and may bereadily attached to a pump of any description, being adapted for use inconnection with any ordinary hand-pump or with the plunger-rod of anyordinary windmill-pump.

Various changes in the form, proportion, and minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

The combination with a pump comprising a stock 1, avertically-reciprocating pumprod 2, provided at its top with a flattenedor polygonal portion, a bracket 3 extending upward from the top of thestock of the pump and having its upper end extended horizontally,provided with a perforation and receiving and forming a guide for thepumprod, a link pivoted to the bracket and forming a movable fulcrum,and a pump rod or handle fulcrumed on the link and adjustably connectedwith the pump-rod, of an open rectangular frame comprising verticalparallel sides, a lower horizontal connecting bar clipped to the upperend of the bracket, and an upper guide-bar composed of two side pieceshaving parallel end portions and oppositely-curved central portions 13,forming a guide-eye, the upper ends of the side pieces being bent inwardover the parallel portions of the upper bar to form housings, a pair ofsprings having their upper ends arranged in said housings and adjustablyconnected with the top of the frame, a cross-bar 17 attached to thelower ends of the springs, provided with a central opening to receivethe pumprod and having a clamp, whereby it is adjustably secured to thelatter, and a brace disposed substantially vertical and extendingdownward over one side of the rectangular frame to the lower portion ofthe stock of the pump and secured to the same, substantially asdescribed.

In testimony that l claim the foregoing as my own l have hereto affixedmy signature in the presence of two witnesses.
